    摘要: A data processing method includes the steps of: initializing a syndrome vector to be an (n−1)th symbol; finding a corresponding mask based on the syndrome vector, wherein the mask is zero when the (n−1)th symbol is zero; correcting a known constant, which is zero when the syndrome vector is zero, based on the mask; inputting the syndrome vector to a log look-up table to correspondingly find log data; performing a modulo addition operation corresponding to log maximum data to find a log sum based on the log data and a log known constant; and inputting the log sum to an anti-log look-up table to correspondingly find operational data.

    摘要: During a method, a modulus circuit determines a modulus base p of a first number and a modulus base p of a second number. Also, the modulus circuit performs the operation using the modulus base p of the first number and the modulus base p of the second number, and calculates a modulus base p of the result of the operation involving the first number and the second number. Next, the modulus circuit compares the result of the operation carried out on the modulus base p of the first number and the modulus base p of the second number with the modulus base p of the operation performed on the first number and the second number to identify potential errors associated with the operation. Moreover, the modulus circuit repeats the method to identify additional potential errors associated with the operation, where the determining and calculating operations are repeated using moduli base q.

    摘要: A decoder, encoder and corresponding system are disclosed for providing fast Forward Error Correcting (FEC) decoding and encoding of syndrome-based error correcting codes. Three-parallel processing is performed by elements of the system. More particularly, in an illustrative embodiment, a decoder performs three-parallel syndrome generation and error determination and calculations, and an encoder performs three-parallel encoding. Low power and complexity techniques are used to save cost and power yet provide relatively high speed encoding and decoding.

    摘要: Various methods and systems for implementing Reed Solomon multiplication sections from exclusive-OR (XOR) logic are disclosed. For example, a system includes a Reed Solomon multiplication section, which includes XOR-based logic. The XOR-based logic includes an input, an output, and one or more XOR gates. A symbol X is received at the input of the XOR-based logic. The one or more XOR gates are coupled to generate a product of a power of α and X at the output, wherein α is a root of a primitive polynomial of a Reed Solomon code. Such a Reed Solomon multiplication section, which can include one or more multipliers implemented using XOR-based logic, can be included in a Reed Solomon encoder or decoder.
